Global SMOS SSS maps

Global SSS maps are computed at BEC using a new methodological approach to cope with land and RFI contamination.


Two different products are generated


Daily map of 9 day  in a rectangular grid at 0.25º resolution, from 2011 to 2019. Some of the improvements of the v2 product with respect to the previous versions are:

i) latitudinal and seasonal bias has been reduced; 

ii) new filtering criteria have been applied to be more consistent with the geophysical signal;

iii) an estimate of the salinity uncertainty is provided in the L3 product.


Daily fused with OSTIA SST maps in a rectangular grid at 0.05o resolution, from 2011 to 2019

These maps have been validated with near-surface measurements provided by Argo profilers, which allow us to define several quality metrics.
